Angular velocity change control

The inverter itself does not have a function to detect the rotation angle and change the velocity accordingly. Therefore, to implement required control, it i... More Details >>

DC injection brake

1. The braking torque can be considered 50% of the motor rated torque.2. The largest stress the DC injection brake gives to the motor is the motor heat gener... More Details >>

Inverter communication

Check if the communication setting parameters (Pr.117 to Pr.124) are set to the same values between the inverter and personal computer.Note that communicatio... More Details >>

FR-A800 "Parameter for the communication setting"

These parameters are used for the communication compatible with the communication protocol of the Ethernet IP of the HMS optional circuit board (A8NEIP_2P). More Details >>

S-shape acceleration/deceleration of the FR-D700

It does not change even when General-purpose magnetic flux vector control is performed. Pr.3 is the inflection point of the S-shape. More Details >>

Terminal response time

It is 2 to 3 ms. By setting Pr.289 Inverter output terminal filter and Pr.699 Input terminal filter, the FR-A700 can be compatible with the response of the t... More Details >>

Carrier frequency automatic reducing function

The function operates immediately when the current of 85% or higher flows. The limit is canceled when the current becomes 80% or lower. More Details >>

FR-F800

Yes, the current is limited under the PM sensorless control. More Details >>

Communication specifications for connection of multiple inverters

Use the RS485 terminal for the multiple communication of the A series/F series inverters.* Communication with the PU connector is only one-to-one connection. More Details >>

Gain adjustment under the speed control

Since the lower limit has been internally set, 3% or less is recognized as 3%. More Details >>
